Your statement is not a rumour. Some people live under great financial pressure.
They have to try every way to get a job. Some people like Java programmer's high pay but they have no patience to sit down reading Java books. In addition, some company training centers are producing Java programmers in a very fast pace. I think
this phenomenon will cease once Java is no longer hot.

I think it is not a good idea to pretend a Java programmer. However, I think it is Ok to do some decorative things in our resume.

Here is a story I heard in Toronto. One manager in a small company received 5 resumes from Chinese guys. These resumes are so silimar to each other that
he he became suspicious. He decided to interview 5 candidates and hire the best one
he think. However, he fired the lucky guy after one day.. The reason is that this guy did not know what he claimed to know.
